Hi all,

I have been reading through many posts on the forum about the VOF model used in FLUENT and it's capabilities. I am however still slightly confused about one matter:

Is it possible to use the VOF model while also incorporating a surface tension that varies with temperature along and interface?

If so, how is this accomplished? Perhaps through a UDF or define/phases/interaction...?

I would like to model Marangoni or thermocapillary flow as air bubble grows in a liquid silicone oil layer.

Any help anybody can offer will be greatly appreciated.

P.S. I am using FLUENT 6.2.16 and also have access to 6.3 if necessary!

i haven't try this before but i thought the UDF able work with the surface tension varies with temperature
